ASSEMBLY
CRANKSHAFT ADAPTER
If necessary remove the four cap-screws from the crankshaft pulley. Then install
the crankshaft adapter and spacer to the pulley with cap-screws and lock-washers
as shown in the parts section.
FRONT PUMP MOUNTING
Install the pump mounting bracket on the front of the tractor with cap-screws and
lock-washers as shown in the parts section illustration. DO NOT tighten fasteners at
this time.
Slide the pump drive shaft into the crankshaft adapter. The end with the shorter
splines should be inserted into the adapter (if applicable).
Slide the splined drive shaft coupler onto the pump drive shaft. Install the pump
onto the mounting bracket. NOTE: the shaft is offset to one direction, the pump
should be installed with the offset side on top. Install hardware for securing pump to
the pump mount, DO NOT tighten.
Align pump so that splined coupling can be moved back and forth by hand. Tighten
pump mounting bolts in succession rechecking for spline coupling movement.
Remove the pump mounting bracket bolts one at a time and apply a thread locking
agent. Tighten these bolts in succession, again checking for free movement in the
drive shaft. After all bolts are torqued, the end play on the drive shaft should be 1/16”
to 1/8”, and coupler should move freely with hand pressure. If end play is less than
1/16”, grind the end of the shaft to achieve the proper end play. If there is more than
1/4" of end play, return the shaft with specifications for a longer shaft.
CAUTION: DO NOT START THE TRACTOR UNTIL ALL HOSES ARE
ATTACHED, TANK IS FILLED WITH PROPER OIL AND BALL VAVLES ARE OPEN!
STARTING AT THIS TIME WILL CAUSE SERIOUS DAMAGE TO THE PUMP.
ADJUSTING REAR WHEELS
Raise rear of tractor onto jack-stands. Follow the instructions in the tractor
owners manual for adjusting tires and rims to 72” center for side mounted
mowers and 79.8” for boom mowers. NOTE: This may require switching the
wheels to opposite sides of tractor.
MAIN FRAME MOUNTING
Raise front of tractor as needed and slide the main frame under tractor from right
hand side. With an overhead hoist and / or jack-stands, raise the frame up to the
correctly matching mounting holes. Install spacer blocks and shims as needed.
Install cap-screws and all other hardware as shown in main frame parts section.
Remove the cap-screws one at a time and apply a thread locking agent, then reinsert
the cap-screws and tighten / torque to values noted in the torque chart located in the
maintenance section of this manual.
